After deploying a vSAN cluster, the need sometimes arises to make changes to its network configuration, such as migrating the vmkernel network of the cluster to a new subnet. This requirement may appear for example when changing the network in which the vSAN cluster is running, or even, in a more complex scenario such as […]

Over the last 6-9 months, I have been reviewing the vast majority of a new book just released to print by Frank Denneman and Niels Hagoort – The vSphere 6.5 Host Resources Deep Dive. This book is, without a doubt, the most in-depth look at host design I have ever read, we are not talking […]

Following on from my previous post on configuring custom ESXi images for PXE deployment, it piqued my interest again in Auto Deploy, now that I have a lab large enough (enough physical failure domains) to justify auto-deploy I figured i’d give it another go. I have chosen to implement stateless caching as it will allow […]

I have been testing out Runecast Analyzer in my lab recently – it’s pretty badass, you can set it up to scan your virtual infrastructure at a vCenter level and will scan your vC, VMs and hosts looking for KBs that may apply, security compliance and best practises. As you can see my lab isn’t […]

I have been working with VSAN in the lab recently and had the need to get some deeper stats on the inner operations. I had upgraded the lab to ESXi 6.0 U1 and vCenter 6.0 U1 and for the life of me couldn’t get the RVC console in the VCSA to work per the VMware […]

A slip of the tongue earlier in the month mentioned that the release date might be March 12th, and here we are. You can download all the vSphere 6.0 goodness from the newly revamped my.vmware.com Docs available here. As always, it’s just out, don’t roll it right into production, without checking out known issues, your […]

I have come across a number of environments where mystery “snapshot” files exist – they are not seen in snapshot manager, running a consolidation them doesn’t help, creating a snapshot (with memory, or guest OS quiescing) then running “Delete All” doesn’t resolve it, but some applications still think a snapshot is there. To take care […]

The new version of vSphere brings some major improvements to the vCenter management end of things, the main thing is that it is now a highly available solution (previously reserved for vCenter Server Heartbeat – a separate, now EOL, product VMware offered) that can run in two modes.

Multi-NIC vMotion is a no-brainer configuration for performance: Faster maintenance mode operations Better DRS load balance operations Overall reduction in lead time of a manual vMotion process. It was introduced in vSphere 5.0 and has improved in v5.5 – so let’s get into how to configure it (we’ll be using the vSphere Web Client because […]
